expected to employ 7,500 people during peak construction and create 4,000 long-term jobs

Development activity has been slowed, and the project is under review until mid-2027 due to escalating security risks, assessing scope, timeline, capital requirements, and financing. Previously targeted first production by end of 2028 is under review, with anticipated significant capital budget increases.

Production overview - 2024: copper 7300000 t, gold 13000000 oz.

The project will be a truck-and-shovel open pit operation. The processing facilities will produce a high-quality copper-gold concentrate. Mined rock will be crushed and ground before being fed into the process plant. Construction is planned in two phases with a combined process capacity of 90 million tonnes per annum.

During peak construction, the project is expected to employ over 7,500 people. Once in production, it is projected to create between 3,500 and 4,000 long-term jobs.

The project is a greenfield, open-pit mining operation. As of early 2026, Barrick has slowed development activity and is conducting a project review until mid-2027 due to escalating security risks in the region. This has led to an anticipated increase in the previously disclosed capital budget and a delay in the timeline, with the first production target of late 2028 no longer certain. The project is planned to be constructed in two phases. The Environmental and Social Impact Assessment (ESIA) for the project was approved by government authorities in early 2025. Fluor was selected as the lead engineering, procurement, and construction management (EPCM) partner.

The construction is planned in two phases with a combined process capacity of 90 million tonnes per annum. The initial phase is expected to produce 200-250 kilotonnes of copper per year. A potential expansion could increase copper production to 400 kilotonnes per year. Another estimate for annual production is 200,000 tonnes of copper and 250,000 ounces of gold. The project is expected to produce 700 kilotonnes of gold and copper concentrate annually for export.

The operation will be a truck-and-shovel open pit mine with processing facilities to produce a high-quality copper-gold concentrate.

expected to exceed 3,200 employees by the end of 2024

The San Juan Silver project is a high-impact exploration and pre-development project located in the historic Creede Mining District of Colorado. Hecla Mining Company holds full ownership of the entire 21-square-mile district, a consolidation of the prolific silver-producing area for the first time. The project's focus is on the historic Bulldog mine, which produced 25 million ounces of silver between 1969 and 1985. The project is currently in the exploration phase, with a strategic goal of advancing towards accessing underground infrastructure for resource confirmation and expansion. Hecla's 10-K filings confirm the project holds a 112-d2 mining permit from the Colorado Division of Reclamation, Mining and Safety (DRMS) and a Mining Plan of Operations with the U.S. Forest Service (USFS). The total project area covers 13,645 acres, comprising 129 patented lode and millsite claims, fee lands, and 704 unpatented lode claims.

Production overview - 2025: silver 36760000 oz, gold 26000 oz, lead 49270 t, zinc 40310 t.

The Greens Creek ore body contains silver, zinc, gold, and lead and is located within the Admiralty Island National Monument. It is the only mine in the United States congressionally designated to operate in a national monument. The property includes patented lode and mill site claims, property leased from the U.S. Forest Service, and mineral rights on adjacent federal land, encompassing a total of 23-square miles. Access to the entire project is by boat. Copper became a payable metal for the mine in 2024, creating a new revenue stream.

Production overview - 2025: silver 8700000 oz, gold 59349 oz; 2024: silver 8500000 oz, gold 55275 oz.

The mine operates an ore concentrating mill that uses a flotation process to produce silver, gold, zinc, and lead concentrates. The processing facility includes a SAG/ball mill grinding circuit to grind the ore. The mine produces approximately 2,300 tons of ore per day. In 2024, 46% of tailings were reused as backfill.

The mine uses tele-remote and battery-powered load, haul, and dump equipment to reduce ventilation requirements and improve worker safety. It also utilises Safescape Laddertube.

In November 2024, the U.S. Forest Service announced a final decision to extend production at the mine for 12 to 18 years. This extends operations past 2031 until at least 2043. The expansion of the tailings disposal facility will occur in two phases, with the first phase beginning immediately to provide additional capacity over three years.

The Greens Creek Mine, operated by Hecla Mining Company, is an underground mine on Admiralty Island in the Tongass National Forest, approximately 18 miles southwest of Juneau, Alaska. It is one of the largest and lowest-cost primary silver mines in the world. The mine operates 24 hours a day, 365 days a year, producing about 2,300 tons of ore per day. The primary mining methods are cut-and-fill and long-hole stoping. In addition to silver, the mine produces zinc, gold, and lead.

Production overview - 2026: silver 2.2 Moz, gold 13000 oz; 2025: silver 8.7 Moz, gold 59349 oz, zinc 51.3 kt, lead 18.2 kt.

The operation uses flotation and gravity processes to recover silver, gold, lead, and zinc. Major facilities include the underground mine, an ore concentrating mill, a dry stacked tailings facility, a ship-loading facility, and camp facilities. Since 2009, hydropower has provided 77% of Greens Creek's energy needs. Metallurgical recoveries in 2025 were 79.3% for silver, 74% for gold, 82.6% for lead, and 88.8% for zinc. In the first quarter of 2026, Greens Creek achieved a record for underground backfill placement, placing nearly 164 thousand tons. Hecla is also evaluating the economic potential of developing a pyrite concentrate circuit at the mill to boost silver and gold recoveries.

In January 2026, the Federal Permitting Improvement Steering Council announced that the Greens Creek Surface Exploration Project had completed its federal permitting process. The U.S. Forest Service approved a five-year plan of operations for surface exploration to identify new mineralised targets for silver, gold, lead, and zinc, which is expected to extend the mine's life. Hecla plans to nearly double its 2025 investment in exploration in 2026, with a focus on Greens Creek among other sites. Capital investment at the mine is also directed towards the expansion of its tailings facility, which is expected to increase tailings capacity to 2045.
